TT on Symposium Super Segue - slate or maple underneath?


I've gotten a Super Segue for my VPI Avenger. I have various things on hand I can place under the Symposium. I wasn't sure if a 3" thick maple block would work better than a 1/2" thick piece of slate. The whole thing will be sitting on top of my wooden equipment rack. I know ideally I should try both to see what sounds better, but hauling a 70+ pound TT on and off shelves for listening tests (not to mention moving a 3" thick maple block around) can be a bit of a pain. I'm hoping someone here has had some experience with what they've felt works best under a Segue, so I could try that first.

If your floor is not on concrete a good suspended turntable would be preferable and nothing you can do is going to isolate the table from low frequency disturbances like footfalls.
I'm not sure why you make this claim but you are completely mistaken. Perhaps you use a lightweight table that suffers such problems, but your claim definitely doesn't apply to all turntables.
@bdp24 - thank you for your response/comments. I think I'll try something similar. Not sure yet, will need to think about it and see what's available locally. 
Well, I decided my first experiment will be (and is) the TT feet in Supercouplers, which are resting on Super Point Pods, which are sitting on a 3” Maple platform, which itself is sitting on a 13 layer Baltic Birch ply platform. I’m listening to this for a while before I decide if I want to try ASC Walldamp between the Maple and BBirch. So far I like what I’m hearing.
